The Marathon MM Series of infrared (IR) thermometers has been updated with an optional motorized, remote-controlled variable target focus capability for additional flexibility for target focusing in a wide range of industrial temperature measurement applications. The Series now enables users to adjust the focus of measurement targets, either by push-button at the rear of the instrument, or remotely via an RS232/RS485 PC connection, where adjustments can be seen real-time through video. Users can select from either standard fixed-focus sensors or sensors with the new variable focus option, both with a focus range between 200 mm and 2.2 m (8 in and 7 ft). Close-focus Marathon MM sensors are also available with fixed optics enabling targets as small as 0.5 mm (0.02 in.) to be measured from a distance of 150 mm (6 in.).
